ABSTRACT  |  'Jaegul Choo (https://sites.google.com/site/jaegulchoo/ ) is an assistant professor in the Dept. of Computer Science and Engineering at Korea University. He has been a research scientist at Georgia Tech from 2011 to 2014, where we also received M.S in 2009 and Ph.D in 2013. His research focuses on visual analytics for high-dimensional data, which leverages both data mining and interactive visualization. *************** abstract Visual analytics, which leverages human exploration via interactive visualization in data analyses, has recently gained popularity. Data mining methods often play a crucial role in visual analytics by providing an important insight about data. In this talk, I will present both fundamental approaches and visual analytics systems that join forces from data mining and visual analytics. First, I will introduce a visual analytics system called the FODAVA testbed where users can obtain crucial understanding of data by applying various data mining methods in an interactive visual manner. Second, I will present another system called UTOPIAN (User-driven Topic Modeling based on Interactive Nonnegative Matrix Factorization), which re-designs computational methods for supporting various user interactions with real-time responses in visual analytics. Several usage scenarios of UTOPIAN will be presented using real-world data sets. Finally, my on-going work and future directions will be discussed.
